From my observations, "Nods off a lot" seems to be a characteristic that indicates HP being the highest IV. Incidentally, I've never seen a "Takes plenty of siestas" Pokémon without perfect HP, and I can't think of any characteristics that might have been removed besides "Often dozes off" which just happens to have a similar meaning to both of the new characteristcs. Once PokeBank opens up this'll get easier, but I'm almost wondering if Siestas indicates a 31 HP IV and only a 31 HP IV, and "Nods off a lot" indicates 1, 6, 11, 16, 21, and 26.

For now, the Siestas one I put as HP Mod 1 (so 1,6,11,16,21,26,31). As for the others, I would need to know the exact IVs of a Pokemon with each of those characteristics and I could figure it out easily.

Yep. Hidden Power Type is totally unrelated to Hidden Power Attack Power. However, the Fairy type may screw it all up. Either Fairy cannot be a HP type (like normal) or it took a slice out of some other HP Type's pie... I have no idea about that yet, so using HP Type in the IV calc could be "risky". :)

Dunno if it could help you, but some stuff I heard about characteristics. Firstly, they were changed simply because they were mistranslated in previous gens. So it's more of a correction. Secondly, both reddit and now serebii say that "nods off a lot" = "often scatters things", and that seems likely, considering there was always a second similar characteristic - "scatters things often". That also corresponds with Arcticblast's observations earlier, with this characteristic being connected to HP. I've also seen few pokes with "scatters things often", but not a single one with "often scatters things". Lastly, I have a Goldeen here:

Has anyone figured out what "high and dry" and "is terrible" etc. imply? I realize they're not that important but it might be useful for Trick Room spreads and really situational Destiny Bond sets. And people seem to have a hard-on for giving already-weak special attackers 0 Attack IVs to minimize confusion damage.

Thanks a lot for the calculator, MetalKid! I've been using your calculators for a long time and they are the best of all I've tried. I was really, really happy when you updated yours for Gen VI monsters.

Thanks. My site really needs a face lift. The last 2 years I've done nothing but web development with jQuery, Javascript, and Kendo UI (www.kendoui.com) [I'm actually a C# .NET programmer as a career]. I'm excited to show you guys what I can do nowadays! :) (It is just tough to find time when you have a 2 year old daughter running around...)

Prerequisites:
- Have your Pokemon evaluated by the Judge in Kiloude City Pokemon Center
- Find out your Pokemon's Hidden Power from a man in Anistar City
- keep track of your Pokemon's EVs (or use a Reset Bag)
- use Metalkid's IV calculator: http://www.metalkid.info/Pokemon/Calculators/IV.aspx

If you have access to multiplayer battles:
- bring six Pokemon into a battle with another Trainer with the Level 50 rule set - they will be auto leveled to 50 and you can check their IVs

If you do not:
- have a few Rare Candies on you
- using Metalkid's IV calculator, record your Pokemon's stats each time you use a Rare Candy on it in the stat field (be sure to adjust the level!)
